SPECIFICATION forming part of Letters Patent No. 433,705, dated August 5, 1890. Application filed March 23, 1889. Serial No. 304,428. (No model.)

To all whom it WMbZ/COYLOWVL:

Be it known that I, EUGENE F. TRENT, of Jersey City, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Heaters, of which the following is a specification.

My improvement relates to heatin g-dru ms into which a lamp or burner of any suitable kind may be inserted for the purpose of heating the air within the same and producing a circulation of air through it.

I will describe a heater embodying my improvement in detail, and then point out the novel features in claims.

In the accompanyingdrawings, Figurel is a partial side view and partial longitudinal section of a heater embodying my improvement, the section being taken atthe plane of the dotted line 00 m, Fig. 2. Fig. 2 is horizontal section taken at the plane indicated by the dotted line y 3 Fig. l, the lamp which is shown in Fig. 1 being omitted in Fig. 2. Fig. 3 is a horizontal section or View of the drum, taken at the plane of the dotted line z a, Fig. 1. Fig. 4 is an inverted plan or bottom view of the drum. Figure 5 is a side view of a drum embodying myimprovement employed with a gas-burner, a portion of the drum being broken away or removed to expose the gas-burner and the appurtenances thereof to View. Fig. 6 is a horizontal section taken at the plane of the dotted line to w, Fig. 5.

Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1, 2, 3, and 4, A designates the body of the drum. It is made of cylindric shape in the present example of my improvement. It is preferably made of sheet metal, such as sheet-brass. It is perforated at numerous points. In the present instance it has in the lower portion rows of perforations a and shortly above these other rows of perforations a Still higher up it is provided with a row of oblong perforations or slots a Still higher up it is shown as having another row of oblong perforations or slots (6*. Higher than these is another row of 0blong perforations or slots a and near the top it will be seen that another row of oblong perforations or slots a exist.

Air is free to enter the rows of perforations a a There is no passage for air through ZLIICG.

the perforations (t (1,, or a in the present ex.- ample of my improvement, because inside the shell opposite these rows of perforations a a ail have fitted strips of mica b 5 b These strips of mica are held between bands 1), secured inside the shell by solder or any other means. For each strip of mica there are two opposite bands Z), and the adjacent edges of the opposite bands are bent inwardly toward the center of the shell and then downwardly, so as to lap over the edges of the mica. This manner of securing the mica may be readily understood by reference to Fig. 1. Air may escape from the upper row of perforations a.

A shell constructed as I have described presents a very tasteful and attractive appear- Light will shine through the rows of perforations a o a because, although the mica will prevent the passage of air through these perforations, yet it will permit rays of light to pass through the same.

I have shown the shell as provided with handles a, which may consist of arms of metal secured by rivets or otherwise to the shell, and embraein g between them a cylindric roller of wood. These handles serve as a convenient means for lifting and carrying the drum. The drum at the lower portion of its length is provided with a door A. This door consists of a segmentof the drum. It is connected at one edge to the main portion by hinges 64 so as to be free to swing laterally, as indicated by the dotted lines in Fig. 2, and provided at the other edge with a catch, here shown as consisting of a rotary pin a pivotally connected with the door and having affixed to it a hook-shaped catch a which, when the door is closed, may hook over an arm a secured upon the main portion ofthe drum. This door aifords facility for inserting and removing a lamp or burner or any appurtenant part to a lamp or burner. It also affords access to the same while there in place.

At the lower end of the drum A there is a flange A This is shown as having an upwardly-extending rim a entering the lower end of the drum. This flange A flares outwardly and has secured to its lower portion a plate A forming the bottom of the drum. As shown, the outer edges of the plate A are bent downwardly in contact with the inner surface of the lower edge of the flange A and secured to the latter by any suitable means, in the present instance by small screw-bolts and nuts a The drum is shown as supported by legs A, which may be made of cast metal, and have at the upper end h orizontallyextending portions which flt against projections a with which the bottom plate A is provided, these projections being made in a similar manner out of pieces of sheet metal properly bent and attached to the plate. The legs are shown as secured to the projections by screws and bolts o It will be observed that the central portion of the bottom plate is depressed downwardly to form a cavity at, suitable for receiving a lamp or stove C, and that the outer port-ion of the bottom plate beyond this cavity is provided with perforations a, through which air may enter and whence it may ascend through the drum. It will also be observed that the flange A is provided with perforations a, through which air may enter to the drum.

The lamp or stove O is of the type generally known as a central-draft lamp, it having an annular wick-tube, an outer air-distributer.c, through which air may pass to the outer surface of the flame, and a central draft-tube 0 through which air may ascend to the inner surface of the flame. It will be observed that this lamp is supported by legs 0 which fit in the central cavity (1/ in the bottom plate of the drum, so that the lamp will be centered.

The bottom plate A has a central opening 0. the edges of which are turned upwardly to form a flange or rim. In this flange or rim is telescopically or adj ustably fitted a flue D, which may be made of sheet metal and of cylindric form at the lower part and flaring at the upper'part. The lamp-reservoir, it will be observed, has in the bottom a central elevation, forming a cavity in the under side. It will be noticed that the central draft-flue starts from this elevation in the bottom of the lamp-reservoir. The flaring upper portion of the flue D fits against the under surface of the central elevation in the bottom of the lamp-reservoir, and hence air which enters the opening a in the bottom plate of the drum will pass upwardly through the flue and enter the central draft-tube 0 Below the central opening e is a drip-cup E. This is made in the form of a cup having a flat bottom and flaring sides and an upwardly-extending flange at the upper edge. The sides are provided with slots 6 at a distance above the bottom. The flange at the upper edge is secured to the bottom plate of the drum by clips which overlap the flange and are riveted or otherwise secured to the drum.

G designates a collar. This is shown as composed of two portions, an upper cylindric portion g and a lower flaring portion g. It is supported by means of brackets or clips g secured to the drum and extending under the lower edge of the flange-like portion 9 This collar is somewhat smaller in circumference than the drum, so that there may be a pas sage of air between it and the drum. Extensions g serve to center the collar. The body of the lamp 0 is some distance below the flange-like portion 9 and the burner of the lamp is considerably smaller than the cylindric portion g. A circulation of air may therefore pass upwardly from the lower portion of the drum around the burner of the lamp. This collar G may be lifted off the brackets 9 It may be slipped over the lamp and the lamp may be introduced with it through the door A. This collar G is an important feature in that it prevents the air from ascending directly upward through the drum and insures a proper amount of air passing to the outer air-distributor c of the lampburner. It keeps the body of the lamp cool by carrying the induced air over the oil-fount and passes it in a heated condition to the top. This collar may be detachable.

At the upper end of the drum A, I have shown an outwardly-extending flange A The drum has a top plate e fitted to it. This :top plate has a cylindric flange a. This is secured by bolts and nuts e to the drum.

A is a removable cover having a lower cylindric portion 0, adapted to flt within the flange a of the plate a and having an upper perforated portion through which air and the products of combustion which may enter the cover can escape. The top plate c0 has a central opening a, the edges of which are here shown as upturned. Beneath this plate a slide or damper c0 is arranged. It is secured to one end of a lever (1/ This lever is pivoted to the plate 04 by a screw a. The outer end extends through a slot in the drum. By oscillating this lever in one direction the damper may be made to cover the opening (4 By oscillating it in another direction the opening a may be uncovered, so as to allow air and the products of combustion to pass from the drum through the top plate 0L The upper surface of the plate e is provided with projections a Upon these a saucepan or other cooking utensil Il may rest. WVhen the damper c0 closes the top plate a the heated air and products of combustion escape into the apartment in which the drum is arranged from the perforations a.

Turning now to Fig. 5 it will be seen that the drum is the same as that already described. Here I have shown a gas-burner I as used instead of the lamp 0, which I have represented in the previous figures. The same collar G is here employed. Gas is supplied to the burner by a pipe J under control of a cock J.

As shown in Fig. 6, the collar G is composed of two horizontal sections or half-collars, one section of which maybe attached to the door of the drum, so as to move outwardly when the door is opened to remove or rearrange the lamp or burner, and the other section is permanently secured to the main portion of the drum.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a perforated drum having a damper in its top plate and a central-draft lamp communicating with a central flue rising from an opening in the bottom of the drum, of a collar consisting of a flaring lower portion and a cylindric upper portion, the said collar being removable and surrounding the burner and diverting air ascending through the drum to the burner, substantially as specified.
